CARPET SWEEPER AND CLEANER.

To all whom 'it 'may concern:

Be it. known that I, JAMES M. SPANGLER, a citlz'en of the United States,residing at Canton, in the county of Stark and State of Ohio, haveinvented a new and usefularpet Sweeper and Cleaner, wherein means areprovided for brushing and loosening dust and dirt from carpets, rugs,floors, &c., wherein provision is made for pneumatically lifting saiddust anddirt and depositing the saine in an appropriate receptacle, andwherein means are provided for preventing the suction of said sweeperfrom lifting the said carpet, rug, or other floor-covering intoengagement with the mechanism not in- 'tended for engagement with saidioor covering.

'1`he object of my improvement is to provide acarpet sweeper and cleanerof simplilied form and `of great efficiency and this, together withother objects readily apparent to those skilled in the art, I attain bythe construction illustrated in the ing drawing, in which- Figure 1 is avertical section of the casing, said section being taken on -adiametrical plane and illustrating the electric-motor and itsconnection. Fig. 2 is a bottom or underside view of the fan casingshowing the fan and its parts in proper relative position but on areduced scale. A

In the drawing similar numerals of reference indicate similar parts.

The numeral 1 indicates the floor.

2, is the carpet or fioor covering.

The fan casing 3 is partially of circular form and provided With the top4, and the lower inwardly extending annular angej. The said' casing ismounted upon suitable wheels or casters 6 and 7 for the purpose offacilitating the movement of the sweeper over the floor. In the casingand to an opening 7a (shown partially in dotted lines) is provided,which leads througha discharge passage in the portion 8 and communicateswith the dust bag or receptacle, 9 attached thereto. f

The top 4 is provided with an aperture, 10, within which` is closelyfitted the casing 11 of an" electric motor. The said motor is firmlyattached to the said top by means of appropriate fastening devices, 11n.The shaft 12 of the motor extends into the fan easing-- 3 and isarranged concentric with the axis of said fan casing. Upon thesaid shaft12V Specification of Letters Patent. Patented Spt. 28, 1909'.

is arranged the hub 13 which is held in lixed adjustment upon said shaftby the set screw 14 or its equivalent. Thehub 13 is provided with aplurality of radially disposed arms, 15, to which the fan blades 16 areattached at an obtuse angle with the shaft 12. The said angle of the fanblades is such that when the electric motor is operated/ the said bladeswill be carried on the arms 15 in the direction to cause an upwardmovement ofthe air in, the casing. The air thus lifted and condensedwill escape through the passage in .the portion 8 and into the bag orreceptacle 9. The lifting of the air in the casing 3 will produce avacuum at the bottom of the casing which is open, except for the annulart flange 5 heretofore described. In accordance with the well knownprinciple, air will rush into the said casing through the said bottomopening carrying with itwhatever dust and dirt has been loosened fromthe floor or iioor covering.

For the purpose of loosening the dust and dirt from the said floor andfloor covering the brushes 17 are provided, which brushes are mounted inthe brush holders 18 attached to the various blades of the fan. It .willbe understood that the said brushes may be otherwise attached to theshaft of the motor.

For the purpose of preventing the suction `from lifting vthe floorcovering into engagement with the fan blades, concentrically arrangedrings, 19, are attached to the fan blades by solder or other appropriatemeans of connection'.y It is evident that while the suction produced by.the vacuum will have a tendency to lift the iioor covering into thoroughengagement with the brushes 17, the rings 19 will prevent the saidcovering from coming into contact with the fan blades 16, thuspermitting both the brushes and fan to accomplish their differentfunctions with the greatest degree of eiiiciency. A flexible electriccord 20, is electrically connected to the motor and should be connectedto an appropriatesource of electric current. The handle 2,1 is providedwith the yoke portion 22 which is plvoted-l at diametrically oppositethrough the motor thus putting the shaft 12 shaft.

in rapid ro tation. The radially disposed arms l5 together With theblades 16I and brushesl, thereto attached Will be rotated With said Thefan Will `produce a partial Vacuum in the bottom of thefan casing Whilethe brushes will be moved in a circular pathway over the surface of thefloor or floor covering. The dust and dirt thereon Will thus bethoroughly loosened yand lifted by the inrush of air under the annularange,

5 and will be-carried through the exhaust opening and deposited in thebag or receptacle 9. The rings 1-9 Will prevent the tloor covering frombeing lifted too far into the interior of the fan casing and theoperator by means of the handle 2l may move 'the sweeper andy cleanerback-andy forth across the floor, thus subjecting the entire surfacethereof to the sweeping and cleaning action of the device. M

It will be understood that the front Wheels or casters 6 are to belocated-in such position that they Will be entirely outside ofthefansaid discharge outlet, and brushes carried by i said fan blades andadapted for contact with the floor.

2. In a device of the character described,.

a casing open at the bottom and provided with a discharge opening, anelectric motor' mounted in said caslng, said electric motor providedwith a shaft, said shaft being vertically disposed Within said casing,spaced rings disposed across the bottom opening in said casing andbrushes tixedly attached to said `shaft and adapted for Contact with thefloor between said rings.

3. In a device of the character described, a casing provided with anopening in the bottom and with a discharge opening, air

.exhausting means located in said casing and adapted to exhaust the airfrom said' casing through said discharge outlet, a motor mounted uponsaid casing and provided with a vertically disposed shaft, brushesmounted upon said shaft and adapted for Contact with thetioor throughthe opening in the bottoni of the casing, andspaced concentric ringsmounted upon said shaft and adapted to rotate therewith and to preventthe tioor covering from being'drawn Within said casing.

4. The herein described carpet sweeper and cleaner comprising a casingopen at the bottom and having a discharge'opening in the side thereof, afan mountedwithin said casing and adapted to -lift the air in said cas'-ing .from the bottom thereof and 'to expel said air through saiddischarge opening, spaced concentric rings disposed in a plane acrossnthe bottom opening in said casin and brushes adapted for rotary motionin a orizontal plane between adjacent rings, said brushes being alsoadapted for contact with the iioor. f

5. In a device of the character described, a casing open at the bottomand provided With a discharge opening, spaced guards arranged in a planeacross the bottom opening means for expelling the air from said casingthrough said discharge opening and rotatable brushes adapted to' travelin a horizontal -plane and adapted for contact with the tloor betweensaid spaced guards.

6. In a carpet sweeper' and cleaner, the` colnbinatlon of a casing openat the bottom and having a discharge opening in the side thereof, anelectricl motor mounted on said casing, said electric motor providedWith a shaft, said` shaft being vertically disposed within saidcasingfradially disposed horizontal arms ixedly attached to said shaft,fan blades mounted upon said radially disposed arms, saidyfan bladesarranged at an obtuse angle to the said vertically disposed shaft andadapted to lift the air in said casing by their rotation and dischargethe air through said discharge outletbrushes at- .tached to saidradially disposed arms and adapted for contact with the fioor covering,said brushes extending through the opening in the bottom of the casingand spaced con` centric rings mounted upon said fan blades forpreventing contact of said blades With the tloor covering.

In testimony that I claim the above, I have hereunto subscribed mynameinthe presence of two Witnesses.
